Short-distance accurate transportation trolley

Abstract

The invention is suitable for the technical field of transportation devices, and provides a short-distance accurate transportation trolley which comprises a trolley body and a workbench, a trolley seat is arranged at the bottom of the trolley body, and a first moving structure and a second moving structure are arranged between the trolley seat and the workbench; the first moving structure comprises a first rack fixed to one side of the bottom of the trolley seat and a second rack fixed to the workbench, a driving wheel is connected between the first rack and the second rack in a meshed mode and rotationally connected with a bearing plate, and one end of the bearing plate is connected with a driving part. The second moving structure comprises a moving groove fixed to the other side of the bottom of the trolley seat and a fixed rail fixed to the workbench, and the moving groove is slidably connected with the fixed rail. Therefore, the structure is simple, the equipment cost is low, in the short-distance operation process of the trolley body, accurate positioning can be achieved, goods can be stably carried, and the trolley can adapt to the severe environment.

Description

technical field [0001] The invention relates to the technical field of transportation devices, in particular to a short-distance precise transportation trolley. Background technique [0002] Most of the existing transport trolleys are driven by motors as power sources, which have the following disadvantages: [0003] One is that the stop position is the trolley that controls the motor to power off after receiving the signal through the induction switch. Due to the inertia of the transport trolley and the weight of the carried object, the positioning is not accurate. [0004] The second is that the stop position is a trolley that is mechanically positioned, and the trolley rebounds when it hits the mechanical positioner, making the goods loaded on the trolley unstable. [0005] The third is to use the motor with brake for short-distance transportation of the production line. The trolley needs to be started thousands of times every day, which will greatly damage the life of t...

AI Technical Summary

Problems solved by technology

[0003] One is that the stop position is the trolley that controls the motor to power off after receiving the signal through the induction switch. Due to the inertia of the transport trolley and the weight of the carried object, the positioning is not accurate

[0004] The second is that the stop position is a trolley that is mechanically positioned. The trolley rebounds when it hits the mechanical positioner, making the goods loaded on the trolley unstable.

[0005] The third is to use the motor with brake for short-distance transportation in the production line. The trolley needs to be started thousands of times every day, which will greatly damage the life of the motor and brake.

[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
